Product details

Overview

DC2361A from Analog Devices is a demonstration circuit built around the LT3952AEFE monolithic LED driver IC, configured as a 2MHz, 60V boost-mode LED driver with integrated 4A switch. It operates from 8V–28V input (transient to 36V), delivers up to 40V/330mA to a single LED string, and supports PWM and analog dimming for lighting control in industrial and architectural applications.

For engineers reviewing the DC2361A datasheet, DC2361A pinout, DC2361A application, or DC2361A equivalent, this page provides verified topology configuration details, validated efficiency curves at 14V–28V input, confirmed open-LED protection voltage (43.5V typ), spread-spectrum enablement via jumper, and EMI filter bypass options for compliance testing.

Technical Context

DC2361A implements a fixed-frequency 2MHz boost converter using the LT3952AEFE's internal 4A MOSFET switch and dual-loop regulation (constant current + constant voltage). Its feedback network sets LED current via R1 = 0.75Ω (330mA) and output overvoltage protection at 43.5V via R2/R3 divider.

The board supports reconfiguration to buck, buck-boost, or boost-buck topologies using optional components (Q1, R19–R21), and includes adjustable UVLO/OVLO (7.6V turn-off / 9.1V turn-on) and spread-spectrum or external sync selection via the SYNC/SPRD jumper.

Key Specifications

Parameter	Value and Actual Design Meaning
Input Voltage Range	8V–28V operating (36V transient); enables compatibility with 12V/24V industrial rails.
Switching Frequency	2MHz (set by R5 = 40.2kΩ); allows compact magnetics and high-frequency EMI filtering.
Max LED Output	40V @ 330mA; supports medium-power white LED strings up to ~12 LEDs in series.
Open LED Protection	43.5V typical; prevents damage during LED-string disconnection using CV loop clamping.
Efficiency	90% typical at 14V_IN/40V_LED/333mA; minimizes thermal load in enclosed luminaires.
Dimming Support	External PWM (3V logic) and analog (0–1.5V CTRL pin); enables precise brightness control without flicker.
EMI Filtering	Optional ferrite-bead + capacitor on EMI VIN path; simplifies Class B conducted emissions testing.

FAQ

What is the primary function of DC2361A?

DC2361A is a fully assembled demonstration circuit that evaluates the LT3952AEFE LED driver IC in boost configuration. It delivers regulated 330mA current to LED strings up to 40V while providing real-world implementation features including spread-spectrum EMI reduction, open/short LED protection, and dual dimming interfaces - all verified per the DC2361A Demo Manual Rev. A.

Can DC2361A operate in buck mode?

Yes, DC2361A can be reconfigured for buck mode operation using optional components Q1 and resistors R19–R21 as documented in the DC2361A Demo Manual. The standard build is boost-only, but the PCB layout includes footprints and routing to support buck, buck-boost, and boost-buck topologies without redesign - enabling topology exploration with the same DC2361A board.

What are the input voltage limits for DC2361A?

DC2361A operates from 8V to 28V DC input at PVIN or EMI VIN terminals, with transient tolerance up to 36V. Its UVLO is factory-set to turn on at 9.1V and off at 7.6V using R7/R8/R9, and these thresholds can be adjusted by changing those resistor values per the Demo Manual's "Undervoltage and Overvoltage Lockout" section.

How is LED current set on DC2361A?

LED current on DC2361A is set to 330mA by default using sense resistor R1 = 0.75Ω, following the formula I_LED = 250mV / R_LED. To adjust current, replace R1 with a new value - e.g., 0.5Ω yields 500mA - while ensuring peak switch current remains ≤4A and duty cycle constraints at 2MHz are respected per the LT3952A datasheet.

Does DC2361A include EMI mitigation features?

Yes, DC2361A includes an optional EMI filter consisting of FB1 (100Ω ferrite bead) and C7 (0.47µF capacitor) on the EMI VIN path, plus a minimized hot-loop PCB layout. Users may bypass the filter by connecting directly to PVIN, and remove it entirely for base EMI measurements - both configurations are supported and documented in the DC2361A Demo Manual.
